Tuyen Diep

Tuyen Diep serves as a procurement specialist focused on aerospace and aviation systems, managing complex acquisitions within the defense and aerospace sector. Responsible for executing full lifecycle contracting actions, Diep ensures compliance with federal acquisition regulations while aligning procurement strategies with national security and aviation modernization objectives. Their portfolio centers on high-precision engineering solutions, particularly in propulsion systems and mission-critical aircraft components, supporting operational readiness across military and government aviation platforms. Diep works closely with technical stakeholders to define requirements, evaluate technical proposals, and negotiate contract terms that balance performance, cost, and schedule integrity. Diep’s contractor relationships are predominantly with Tier 1 and Tier 2 manufacturers specializing in aircraft engine systems and auxiliary aviation equipment. These include established defense contractors with deep expertise in turbine design, fuel control systems, and avionics integration. While no single vendor dominates the award profile, Diep consistently engages with firms possessing AS9100 certification and DOD supply chain credentials, emphasizing quality assurance, traceability, and sustainment support. Relationships are built on technical rigor and long-term performance, with a preference for vendors capable of supporting lifecycle maintenance and technical data rights. Diep’s contracting approach reflects a strong orientation toward open competition, with 89.5% of actions awarded without set-aside restrictions. However, a deliberate 10.5% of acquisitions are structured as total small business set-asides under FAR 19.5, demonstrating a measured but consistent commitment to small business participation. While no specific socioeconomic categories like 8(a) or HUBZone are predominant, the focus on small business set-asides indicates an active effort to expand the industrial base and foster innovation among niche manufacturers. The primary procurement focus is on NAICS 336412 (Aircraft Engine and Engine Parts Manufacturing), reflecting deep expertise in turbine engines, combustion systems, and powertrain components. Secondary activity under NAICS 336413 involves auxiliary equipment such as starters, generators, and hydraulic actuators. Diep’s technical domain expertise spans propulsion system integration, materials science for high-temperature environments, and compliance with FAA and MIL-SPEC standards, ensuring procurement decisions align with rigorous aerospace engineering requirements.
